PARTITION FOR BUILDINGS.

SPECIFICATION forming part of Letters Patent No. 515,291, dated February 20, 1894.

Application filed May 2, 1892. Serial No. 431,484. (No model.)

0 aZZ whom it may concern.-

Be it known that I, FREDRICK KEPPLER, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented an Improvement in Partitions for Buildings, of which the following is a specification.

Plaster boards or slabs have been made use of for partitions in buildings and the same have been laid together with the slabs or boards edge to edge, and in some instances these slabs or boards have been of sufficient thickness to form the partition, but in most instances they have been nailed or otherwise fastened to studding, or to furring strips upon the floor timbers to form the ceilings of the rooms.

My invention is made for the purpose of strengthening and stiffening the partitions and for rendering the same fire-proof, and by the present improvement the partition can be much thinner than heretofore usual without lessening the strength of such part-ition. I make use of iron stay bars extending preferably from the floor to the ceiling, so as to be firmly connected at the top and bottom ends, and upon these stay bars strips of wood or similar material are secured so as to stiffen the stay bars and at the same time interlock with the grooved ends of the plaster boards or slabs which are set in between the stay bars, and the slabs and stay bars are so constructed that the surfacing plaster serves to firmly unite the ends of the slabs and the stay bars, at the same time that the wall or partition receives its surface finish, thus making a very strong partition and avoiding the necessity of using wooden studding and allowing for the partitions being put up or taken down with great facility and obtaining great strength with but a thin partition.

In the drawings Figure l is a diagrammatic elevation illustrating the manner in which the stay bars are applied between the floor and ceiling. Fig. 2 is a horizontal section at the line A A in larger size and Fig. 3 is a vertical section at the line B B.

The metallic stay bars D are of suitable thickness and width according to the strength required in the wall or partition, and such I stay bars may be either plain and fiat or more or less corrugated, and the. top and bottom ends of the stay bars are permanently fastened in position, preferably by the top and bottom flanges 2, 3, which are turned out horizontally and at right angles to the stay bars,

so as to be nailed, bolted or otherwise fastened to the floor or floor beams at the bottom and to the ceiling, floor beams, transom or other support at the upper ends, and these stay bars are of the proper length for the places that they are to occupy and they are at distances apartsuitable for the reception of the slabs or plaster boards E, and these slabs are of the proper thickness and are preferably made with reeds running lengthwise of the slabs and introduced in the manner set forth in Letters Patent No.'386,102, or such slabs may be made in any other desired manner and of a length suitable to pass in between the respective stay bars. The edges of the slabs or plaster boards are preferably beveled or recessed as at 4 in order that the plastering F may clinch and pass sufficiently into the joints between the slabs to aid in firmly holding the slabs together, and in holding the plastering to the slabs; and the surfaces of the slabs or plaster boards are preferably roughened on one or both sides to receive the plastering or hard finish upon one or-both surfaces. The ends of the slabs or plaster boards are adapted to fit against the stay bars D, and suitable plaster or mortar is introduced between the edges of the slabs and also between the ends of the slabs and the stay bars. I prefer to make use of strips or half round slats G applied to each surface of the stay bars, and these strips or slats are permanently fastened to the stay bars prefo erably by nails at intervals passing through holes bored or punched in the stay bars, and such nails are advantageously of wire passing through the slats and clinched as shown at 5, and it will now be observed that the 5 grooves 6 at the ends of the slabs E are sufficiently large for the slabs to set freely into position and they are secured by plaster or cement introduced into the grooves 6 so as to plaster the ends of the slabs firmly against 10c and to the stay bars and the strips or slats G thereby hold the parts firmly in position as the wall or partition is laid up and the strength of the structure is increased by the plastering F upon the surfaces of the slabs at one or both sides of the partition, as before described. In consequence of the boards or slabs having the grooves 6 in their edges, midway or nearly so, between the two surfaces of the slabs, the stay bars are central within the partition which can be thin and bars with strips or slats secured to the'sides thereof, plaster boards or slabs centrally grooved at theirvertical edges to receive the slats and secured in place by plaster substantially as specified.

3. The partition formed of vertical stay bars with strips or slats secured to the sides thereof, plaster boards or slabs centrally grooved at their vertical edges to receive the slats and grooved on the edges at 4, to receive the plaster, and secured in place by plaster, substantially as specified.

4:. The partition formed of vertical stay bars with strips or slats at the sides thereof, plaster boards or slabs centrally grooved at their vertical edges to receive the slats and grooved and ribbed at their horizontal edges to interlock and secured in place by plaster substantially as specified.

Signed by me this 19th day of April, 1892.
